Viral Evolution

2. This is the capacity of a viral swarm to continue to exist in the presence of selectable pressure.
5. A genetic ____ is a selective pressure that will only enable a small number of genetic variants to replicate.
6. Only segmented viruses can change through reassorting the genomic strands, called genetic ____.
7. All living things and all virus change overtime through genetic ____.
8. A population of RNA viruses that has amplified in a neutral environment, producing millions of progeny all slightly different.
10. Changes in the genetic material that is passed on to future generations.
12. A pressure put on a population that only enables specific variants to survive

1. Evolutionary change occur when the virus is replicating its _____.
3. The adaptive immune responsive, antivirals, and species jumps are all selectable ____ that may push viruses through a genetic bottleneck.
4. Genetic changes occur overtime because the polymerase is ___ and does not perfectly copy the genome every time.
9. If a virus has a low ___ rate, they may not be able to come through a genetic bottleneck.
11. Virus with ___ genomes tend to have higher mutations rates.
12. Genetic changes that do not alter the amino acid sequence.
